INDUCED DRAFT FAN

IS A GOOD INVESTMENT

THE cost of a “ Sirocco ”
, Induced ora ft Plant is
about 30 to 40 °/0 of that of a
chimney of equal capacity.

THE power to drive the Fan
varies from 3/4ths to 2 °/0
of the total power generated,
while the saving frequently
amounts to from 15 to 20 °/„.

INCREASES the steaming
capacity of existing boilers
and thereby increases the
Works production.

REDUCES the Coal Bill be-
cause cheaper coal can be
used than with natural draft.
